[sane-devel] Trouble with network scanning and Umax Astra 2200
Thank you, Henning, for the reply. I just ran scanimage -d net:server IP:test -T, and that passed all the tests. I created the log files you requested, and have pasted them on the web: SANE_DEBUG_UMAX=255 saned -d128 http://narnia.flimzy.com/~jonhall/saned.log SANE_DEBUG_NET=255 scanimage -d net:10.0.2.10:umax:libusb:001:015 -T http://narnia.flimzy.com/~jonhall/scanimage.log Then I rean the exact same scanimage command, but captured the output of: SANE_DEBUG_UMAX=255 strace saned -d128 http://narnia.flimzy.com/~jonhall/saned.strace.log Hopefully this will be of help. I also intend to set up a laptop as a temporary saned server, perhaps this evening or next, if I have time, to see if the same thing happens there. -- Jonathan Hi, On Tue, Sep 27, 2005 at 07:21:30PM -0500, Jonathan Hall wrote: I have a Umax Astra 2200 (the combo SCSI/USB version) connected to a USB port.

[sane-devel] Trouble with network scanning and Umax Astra 2200
I have a Umax Astra 2200 (the combo SCSI/USB version) connected to a USB
port. I can scan locally as root or a user using 'scanimage -d
umax:libusb:001:014 foo.pnm'. I also have it configured such that I can
scan over the network locally (scanimage -d
net:localhost:umax:libusb:001:014 foo.pnm). However, I am unable to
scan over the network from another machine (I've tried with two).
scanimage -L shows the scanner on both client machines:
jonhall@tirian:~$ scanimage -L
device `net:10.0.2.10:umax:libusb:001:014' is a UMAX Astra 2200
flatbed scanner
scanimage -T, however, freezes, and renders the scanner unresponsive until
I power cycle it.
jonhall@tirian:~$ scanimage -d net:10.0.2.10:umax:libusb:001:014 -T
scanimage: scanning image of size 850x1170 pixels at 24 bits/pixel
scanimage: acquiring RGB frame, 8 bits/sample
scanimage: reading one scanline, 2550 bytes...
I ran an strace on saned on the server machine. Here's the last bit (I
can send the entire strace to someone if it would be helpful):
getpeername(7, {sa_family=AF_INET6, sin6_port=htons(51945),
inet_pton(AF_INET6,
fcntl64(7, F_SETFL, O_WRONLY) = 0M
shutdown(7, 0 /* receive */)= 0M
fcntl64(6, F_SETFL, O_RDONLY|O_NONBLOCK) = 0M
select(8, [4 6], [7], NULL, NULL) = 2 (in [4], out [7])M
read(4, \0\0\0\6\0\0\0\0, 8192) = 8M
write(4, \0\0\0\0\0\0\0\1\0\0\0\1\0\0\t\366\0\0\3R\0\0\4\222\0\0..., 28)
= 28
select(8, [4 6], [7], NULL, NULL) = 1 (out [7])M
select(8, [4 6], [7], NULL, NULL) = 1 (out [7])M
The last line repeates infinately until I Ctrl-C, or power-cycle the scanner.
All three machines (server and two clients) are running Debian testing.
The server is running kernel 2.6.8, one client has 2.6.12.4 and one has
2.4.27. The server's USB host controller is an Intel 82371AB/EB/MB PIIX4.
Does anyone have any idea what's going on? Thanks for any help you can
provide!
